//Solution-2: Using Regular Expressions

// function confirmTheEnd(str,target){
//     let reg = new RegExp(target + "$","i")
//     return reg.test(str)
// }
//$ test for end of string or end of line and i means case insensitive in RegExp

//Solution-3: Using built-in endsWith string method
// function confirmTheEnd(str, target){
//     return str.endsWith(target)
//     }
